Building occupants

This is a tool developed by WWF with the collaboration of the Ministry of Agriculture, Food and Environment and the Fundación Biodiversidad. It is aimed at estimating in a simplified way the energy consumption in the household. The objective is to contribute to boost the market for energy rehabilitation of buildings and the promotion of renewable energies through distributed generation and self-consumption.

Display is a communication tool complementary to the national certificate for public buildings that today has most of the Member States. With emphasis on local communication campaigns and providing a variety of communication tools, Display exceeds the requirements of the Directive on the energy of buildings (EPBD) Performance. In particular, post 'evolution' to show efforts and improving the energy efficiency of a building, by including on the same post the energy performance of the building on two years.

11 energy-saving assessment methodologies are used to assess the amount of energy saved as a result of the implementation of specific energy efficiency measures. They include a mechanism to allocate energy savings to each year of the lifetime of the measure concerned.

Pellets energy calculator- The energy calculator is intended to provide  information about the cost difference between conventional fuels and the use  of pellet firing. The calculation determines the approximate heat demand of the building and the annual specific energy consumption of specific geometry of the building, the general data of the thermal boundary and structures.
Thus, the heat demand calculation is only an accurate order of merit, however, sufficient energy prices differencing exact branch enter the expected heating costs.
